SHOEMAKERS JACK. I

Specification of Letters Patent.

Patented July 5, 1921.

Application filed December 6, 1919. Serial No. 342,998. 7

To aZZ whom it may 0011061 72. v

'Be it known that I, IVILLIAM PISKURAN, a citizen of the United States, and a resident of Elyria, county of Lorain, and State of Ohio, have invented certain new and useful Improvements in Shoema-kers Jacks; and I do hereby declare thefollowing to be a full, clear, and exact description oftheinve'ntion, such as will enable others skilled inthe art to 'which it appertains to make and use the same. z I

This invention relates to jacks forrepairing boots and shoes, and one of the objects is to construct a ack of light weight and reduced dimensions, without detracting from the usefulness and efliciency of the same.

Another object is to provide a removable last that fits exactly the shoe undergoing reair. PA further object is to provide means for theiremoving of the tight-fitting last.

Further objects will appear in the ap pended description.

The usual shoemakers jack has a last that can be used on either the right or the left shoe, and it is of such design and shape as to fit shoes of a certain range of sizes. Howshoe even approximately, and it is necessary in nailing on V the shoe from one side to the other as the nails are driven in. The lasts also have a very blunt point, so that they cannot reach up into the usual shaped shoe.-

The tacks, therefore, which are driven into the tip of the toe, do not strike'fthe last and consequently, they are not clenched over, but are retained in place only through friction.

In my improvement I have employed a plurality of lasts that may be readily placed on the last supports, and each of these lasts fit a particular size and style complete set of the lasts can attach the gorrect one to a last support and can then nail the sole on the shoe without taking any pains to shift the shoe around where the tack will hit the last. The metal last on the last support makes a tight fit therewith through-v out the inside of the shoe and all of the nails can be clenched in place without taking any pains whatever. I also proportion the jack in such a way bers in such position'as to produce a very light weight article, that is exceedingly strong and simple in operation,

and use reinforcing'mem- Referring to the drawings:

ig. 2 is a front elevation of the jack, with the last support rotated ninety degrees from the position shown in Fig. 1, the metal last also being removed.

Fig. 3 is a plan of the metal last.

Fig. Q is a section taken on the line A-A of Fig. 2. Fig. 5 is a plan view of the upper support- 1ng member of the jack and a portion of the standard, the last being'removed.

V eferring to the drawings, the jack has a vertical. standard 1. joined to a base 2. In the rear is arranged a web 3 integrally joined to the base 2 and the back of the standard. The standard is, in the main, of channel bar shape, as will be evident from an inspection of Fig. 4. The back portion 4 of the channel-shapedstandard has aslot a holding strap, later referred to.

porthas a socket 14 receiving a post 15, so that the latter may turn freely therein. A set screw 16 fits into a groove 17 in part of the post, so that it may turn freely, but yet cannot be removed without loosening the set screw. On the horizontal portion of the L-shaped support is arranged a rod or bar 18 having a tip 19 adapted to fit into the metal shoe last for purposes of removal, as later described. The post 15 is made hollow, and has an opening, such as 20, on each side. The cavity in the upper part of the post maybe made slightly tapering to receive the projection 21 of the last support 22, the construction preferably being such that the last support may be turned into any desired position for the convenience of the shoemaker.

The last support 22 is not shaped to fit the shoes, but is arranged to have a removable last 23 placed thereon. Any means may be employed for detachably fitting the last to the last support, but, by way of eX- ample, I have shown a ridge 23' adapted part of the last supportis preferably short- 7 sides, Of course,.with

permits 26 on the toe portion that fits against this end of the last support. Each last is'shaped each outfit, all having the lower portion shaped to fit the top part of the last support 22, and the last support being made small enough to accommodate a number 0' the lasts without projecting beyond the l a large number o' lasts more than one'last. support may be used,-probably three last supports in each being very small in size, the other intermediate, and the third, of largesize. The last is preferably left free to move in a direction at'right angles to theplane of the paper in Fig. 1, asthis the shifting of the last from v side toside, in case it does not quite fit the shoe. The upper portion of the standard 1 preferably has a resilient pad27 of leather or wood, against which the forward portion of the support 12,,is adapted to rest when in operative position. This reduces the jar when the nails are being driven into the the jack of the strains Since the 11,1t

In repairing ashoe, the shoemaker will pull the loop 31 otf'of the last and last support by releasingthe foot-lever 8 from the catches 7 cilitated by a spring 32, ifdesired. The proper size and shape of last will then'be selected and placed 'on top of the last support. The shoe'is then placed over the last and last support and the loop 31 placed back over the shoe; The treadle 8 is then depressed by the foot andthe'strap pulls tightly down on the shoe and holds it securely in position. Theshoemaker can then drive thenails' into the shoe sole without manipulating theshoe, as the metal last 23 fits the slice, and each nail driven in will find metal beneath it to clench the point in position. 7
